Description

A kind of livewire work multilayer rubber compound inslation sole

Technical field

This utility model relates at the bottom of rubber monolithic insulated shoes, particularly relates to a kind of livewire work multilayer rubber compound absolutely Edge sole.

Background technology

It is known that at present, when wiring circuit and power equipment are installed or overhauled, in order to prevent, livewire work is unconscious touches And electrical body, meanwhile, also for preventing charging equipment short circuit and human body from exempting from electric shock, use some livewire work to insulate Protective articles is such as: insulator cap, insulation clothing, insulating glove and insulated shoes etc., wherein the rubber insulating shoes of constructing operation personnel dress Sole be monolayer rubber-sole, when wiring circuit and power equipment construction and installation or maintenance, conventional insulator footwear easily skid, Particularly on cable, electric wire, construction is easily skidded, this generation potential safety hazard easy to operator.

Accordingly, at the bottom of power industry is badly in need of a kind of anti-skidding, soft, light, high-low temperature resistant, insulated shoes, song is required Scratch will be good insulated shoes, and in the crucial design at sole of insulated shoes and preparation.

Utility model content

This utility model is to solve technical problem present in prior art, with reference to this utility model people's Patent No.: " preparation method of multilayer rubber compound inslation blanket " of ZL201310344371.7 and Patent No.: ZL201410202583.6's Improve on the basis of " livewire work multilayer rubber compound inslation blanket and preparation method thereof " two utility model patents, expand Exhibition, it is provided that a kind of livewire work multilayer rubber compound inslation sole.

This utility model has broken the footwear sole construction of traditional livewire work insulated shoes, develops one and has multilayer rubber At the bottom of insulated shoes, not only softness but also have anti-skidding effect, on smooth power equipment, particularly electric wire, cable upstream walks safety.

This utility model for achieving the above object, the technical scheme is that a kind of livewire work multilayer rubber is combined At the bottom of insulated shoes, including 3-8 sheet rubbers, the thickness of every sheet rubber is 0.3mm-1.2mm, after 3-8 sheet rubbers are compound Gross thickness be 2.2mm-4.5mm, it is characterised in that: described 3-8 sheet rubber superposition pressings or bonding constitute rubber-covered Sole, rubber-covered sole is the flat-bottom structure without decorative pattern, the described rubber-covered sole edge pressing of a week or be bonded as Body structure, coordinates for contact between every sheet rubber in a circumferential edges.

This utility model has the advantage that and provides the benefit that: it is monolayer that this utility model overcomes conventional insulator sole, Sole is thicker, and winter, hardness was the most hardening, and winter job personnel are worn on cable, electric wire breakneck deficiency of walking, Using multilayer rubber compound inslation sole, livewire work personnel wear multilayer rubber compound inslation footwear and walk on electric wire, The intramarginal every sheet rubber being integrated because of pressing does not all have pinning phenomenon, serves cushioning effect so that it is have flexibility, The effect that flexibility, skid resistance are good, more safer than conventional monolayers electro-insulating rubber footwear；

This utility model provide multilayer rubber compound inslation sole, every layer of sheet rubber ratio is relatively thin, low temperature resistant very well ,- Also keeping soft at 40 DEG C, firmness change is inconspicuous.

In sum, this utility model can be prepared 3 to 8 multilayer rubbers be combined according to different electric pressure requirement At the bottom of insulated shoes, having processing technology easy, flexibility, flexibility are good, the feature such as anti-skidding, high-low temperature resistant, good insulation preformance.
